Description

Technical Field

[0001] The utility model relates to the technical field of outdoor tools, in particular to a nail puller. Background Art

[0002] Tent pegs are tools used to secure a tent, increasing its wind resistance and making it an essential piece of equipment for camping, hiking, and other outdoor activities. Typically made of materials like steel and aluminum alloy, their primary function is to anchor and secure the tent's windbreak cord to soft ground or grass, securing the tent in place and preventing it from being blown away by strong winds.

[0003] Currently, tent pegs are typically installed and removed manually. Manual peg removal involves using tools like crowbars to pull out the pegs, while manual peg pressing involves hammers or other tools to drive the pegs into the ground. Because most tent pegs are long to ensure stability, manual peg removal and pressing requires significant time and effort, and is inconvenient. When installing and dismantling a large number of tents, the need to extract and press numerous long pegs increases the time and effort required, leading to lower work efficiency and even disrupting schedules due to inability to extract and press long pegs on time. Utility Model Content
